v1.9.0 causing 500 POST

[jbstocker]

Describe the bug

Since the 1.9.0 release I have been receiving a 500 error on the POST during the github-release process:

error running command: POST https://github.com/api/v3/repos/{org}/{repo}/releases: 500 []

This started happening only after the 1.9.0 release - a run on May 24th succeeded (1.8.0).

I believe the change to the image to latest is causing the issue.

Reproduction steps

1. Run github-release using 1.9.0 and same configuration as previous versions
2. Experience 500 error

Expected behavior

Not receive a 500 error code for v3 api to github.
